Cryptographic primitives example
WebA common example of this is the messaging tool WhatsApp, which encrypts conversations between people to ensure they cannot be hacked or intercepted. Cryptography also secures browsing, such as with virtual private networks (VPNs), which use encrypted tunnels, asymmetric encryption, and public and private shared keys. Authentication Integrity WebExamples include PGP and its variants, ssh, SSL/TLS, all PKIs, digital signatures, etc For example, a one-way function is a function intended to be easy to compute but hard to invert. ... Other cryptographic primitives include the encryption algorithms themselves, one-way permutations, trapdoor permutations, etc.

It turns out that one-way functions … WebFor example, suppose that for a specific cryptographic primitive (such as an encryption routine), the consensus is that the primitive can only be broken after trying out N different …
WebConsider a primitive element α ∈ G and another element β ∈ G. The discrete logarithm problem is to find the positive integer k, where 1 ≤ k ≤ n, such that: The integer k that solves the equation αk = β is termed the discrete logarithm of β to the base α. One writes k = logα β .
